A novel stepwise micro-TESE approach in non obstructive azoospermia.
BACKGROUND The purpose of the study was to investigate whether micro-TESE can improve sperm retrieval rate (SRR) compared to conventional single TESE biopsy on the same testicle or to contralateral multiple TESE, by employing a novel stepwise micro-TESE approach in a population of poor prognosis patients with non-obstructive azoospermia (NOA). METHODS Sixty-four poor prognosis NOA men undergo...
متن کاملLive birth rates after MESA or TESE in men with obstructive azoospermia: is there a difference?
STUDY QUESTION How do live birth rates compare after intracytoplasmic sperm injection (ICSI) for men with obstructive azoospermia when using sperm derived from testicular sperm extraction (TESE) versus microsurgical epididymal sperm aspiration (MESA)? SUMMARY ANSWER Our study suggests that proximal epididymal sperm (from MESA) result in higher live birth rates as compared with testicular sper...
متن کاملSperm retrieval procedures and intracytoplasmatic spermatozoa injection with epididymal and testicular sperms.
INTRODUCTION Male infertility caused by azoospermia due to non-reconstructable obstruction or non-obstructive azoospermia can be treated by microsurgical epididymal aspiration (MESA) or testicular sperm extraction (TESE) followed by an intracytoplasmatic spermatozoa injection (ICSI). MATERIAL AND METHODS From 9/93 to 6/01, we carried out 1,025 ICSI procedures with aspirated epididymal or test...
متن کاملMicrosurgical vasoepididymostomy for obstructive azoospermia
Infertility is defined as the inability to conceive after 1 year of regular unprotected sexual intercourse. About 15% of couples are affected. Male factors account for about 50% of couples with infertility.1 Approximately 10 to 15% of infertile men suffer from azoospermia—complete absence of sperms in the ejaculate. Among these azoospermic patients, approximately 40% have complete obstruction i...
متن کاملTesticular Sperm Extraction and Intracytoplasmic Sperm Injection: Outcomes in a specialist fertility centre.
Assisted reproduction with testicular sperm extraction (TESE) and intra-cytoplasmic sperm injection (ICSI) are fertility treatment options for couples with severe oligospermia or azoospermia. A retrospective review was performed of 146 TESE procedures in a specialist fertility centre in Ireland. The indication for TESE was obstructive azoospermia (OA) in 59% (n = 80) and non-obstructive azoospe...
